My Supra has an appointment at VIP Performance to get dyno tuned with the new ECU. I'm planning on a test-n-tune 8/12, Firday night at PIR, so I'll see you there after 6PM. I'll be going through Tech in prep for drag racing, so I'll be waiting in line. Stop by and say "hello". Van

Here is a nice short definition for knock and preignition from Hot Rod Mag: "The research octane of ethanol is impressively high, which is a beautiful thing for high-compression and high-boost applications. However, its motor octane (the more extreme standard) is relatively low when compared...

I was surprised by Devin's statement that his 12.1 AF was still safe. I found articles online and did my homework... I see that I need to scale the difference between petrol and e85; Stoich for petrol is 14.7 = 9.7 Stoich for e85. That equates to 34%, so pluggin in your AF petrol 12.1 = 7.9 for...

I've done my study... I see that I need to scale the difference between petrol and e85; Stoich for petrol is 14.7 = 9.7 Stoich for e85. That equates to 34%, so pluggin in your AF petrol 12.1 = 7.9 for e85. Below is a quick scale for comparison purposes: "Fuel ........................ AFRst...

12.1 is a little lean on e85... Stoich on e85 is like, 9.765:1, as I recall. Van

To me this article in Hot Rod Mag , says it all... I'm seriously looking into this fuel. Van

A local provider; you've piqued my interest... O.K., who is it?

Which shop?

Update: Supra drives great w/o any timing pulled due to knock. Power was predictably building all day today while I drove it around town. Spent this evening setting the base timing back to stock, from 8 degrees, and Fatty really pulled nicely up my local hills. A nice improvement over last...

I'm pleased with this ECU's performance. Had it been in the car when we we're at the track, it would have been fun to make a few passes down the 1/4 mile to see what she could have done. Connor, how's you're Supra coming along? Yes, that info on electrolysis, was enlightening ;) Fatty is...

Well, I finally have a good, working JDM TCCS, in the Supra. The old one had issues; pulling timing during WOT pulls from 3K on-ward. Tonight I took Ol Fatty out for a test run (in mid seventy degree temps), she performed flawlessly, w/o pulling timing, the engine building power smoothly, even...

Well, I'm at a loss to say where to look next... It is a good idea to get all known issues sorted to rule them out. I agree with you there. In my experience, the 7M's WOT stumble turned out to be oil in the CPS; R&R'd it and problem solved. I hope your current problem gets similarly resolved...

So this is a new condition which didn't occur before the new turbo? Has anything else been changed on the car? Can you pull any codes? Van

Hey! It was great having met Connor, a guy named Bruce that had a DSM coupe and another fellow Supra owner that showed up with his GF Jennifer. I left at 7PM, just as the Late Night Drags was starting. Some really fast cars doing the 1/4mi in the low 9s! :aigo::burnout: Van

Hey fellow Supra owners! Here's a link to live racing at PIR: NASCAR weekend... PIR Live . Just Log in and enjoy! Van

...just wanted my engine bay to be neat...:: door ::

If you take it in to M&B Cylinder Heads, on Vancouver Way in North Portland, just off the I-5 freeway, you can use my torque plate, for no charge, (I usually charge $200 security deposit), and have Brian at M&B torque plate your block and bore six perfect cylinders. They build wicked Supra...

I'm interested. The secret to speed; BBK and sticky tires! Van

"Steampunk Outfit" Oh my! This is gonna be great fun... See ya' there. D

We've heard this before: "Not every engine is the same..." My built 7M's is still using the TCCS, which pulls ignition timing on occasion, due to knock detection below 4000RPM. EGR is deleated, it is tuned w/AFC NEO, more fuel in the range from 1200-3600RPMs, w/an AFPR and 8 degrees base...
